To ALL TO WHOM THESE IORESENTS .SHALL COME:

Be it Aknown that we, EDwA'nn FARA-UM and GEonGu'W. ScOT'T, of Blackstone, 'in the county of Worcester, and State of Massachusetts, have invented a new and useful Machine for Husking Corn, and do hereby declare the following to be a full, clear, and exact descriptionthereof, reference being had to the accompanying, draw- A ings, making p art of this specicntion, and in which- Figure lA is a top view.- 'Figure 2, a side elevation.

Figures 3 and 4 are end elevationshand A Figure-5, a vertical and longitudinal section of my invention. I The invention consists in the combination andarrangenient of a pair of tinted stripping-rollers'and retaining bars or hold-backs, with two endless hnsking aprons, and supported upon revolving drums or shafts, this combination of parts operating together, and in connection with a chute orrhopper, essentially as hereinafter described.' Y Y' As exhibited in the drawings, the frame of the machine/is. sli-own as composed of a rectangular'frame, a, and a series of posts orrstandards, b b1 b2, a flooring, c, extending partiallylacross the upper surface of. the frane a, serving as a bottoml to a hopper yor chute, ci, for the reception of the tstalks of corn as they are fed along towards the stripping-rollers. These stripping-rollers are Shown at e e1 as having the periphery tinted, and so arranged with respect to ea'ch other that the projections of one roller shall be opposite to the depression of its twin or opposite roller, as shown in fig. 5 of-the drawings, the journals of' these rollers being supported in boxes af al, fixed to the upper parts of the 'posts b b, as represented. The driving-shaft' of'the machine is -shownl at f as supported in suitableV boxes-upheld by bars or braces L hrextending from' the leg vto the leg 61. The rear extremityof the driving-shaft f carries a gear, z', which meshes with a'sinaller gear,'j, fixed to the rear extremity of the journal of the lower stripping-.roller e, and puts the said roller e in'rotation. The oppositeor front end of this roller e carries a pinion, 1c, which engages ywith another pinion, Z, xetl' on the journal of-the upper stripping-roller el, by this means imparting motion to the said roller el. Furthermore, the driving-shaftf carries two bevelled gears m m, which engage .respectively with two other bcvelled gears n nsixed upon the journals of two inclined revolving drums o o, suitably supported in boxes ol o, upheld by cross-bars or braces al n2.,- extending" from the leg b' to the leg b2, there being, further7 two shafts pp upheld by the cross-bars, as represented in the' drawings, and so as to stand upon the same inclinati -n as the drums. Twoendless husking aprons g g are carried by the drums o o, and shafts p p, which are so actuated"by their operating gears as to cause the aprons to travel inwardly towards cach other, and downward, or as shown in iig. 4 of the drawings. Two inclined bars r r are secured to the upper ends-of the posts b b, and extend across from one to the other of' them at the` inner end of the chute d, and in advance of theiluted rollers 'e el, the object of these bars, which I term the hold-backs, being to retain or keep back the ears of corn 'fromjbeing -drawn between the rollers with the stalks. In the operation of the above described machine, the stalks of 'corn with the ears upon them, as they are cnt in the field, are to be placed upon thetloorin'g c, of the hopper'l, and pushed forward between therollers eel.'

The revolution of the rollers will draw the stalk forward and 'break the connection of the ear, theshank orvstub of the ear adhering to the stalk, the car itself, as before mentioned, being kept hack by the barsrr. In this operf ation, a great portion of the husks will be stripped from the ear and carried with the stalk. The ear, with the, husks that may adhere to it, will slide down an inclined bridge, b4, leading from an opening in the loor of the' hopper, and will pass froni thence upon the upper surface ofthe revolving aprons gg, which will seize and carry between them and strip from the ear its remaining husksVthe close proximity of the vaprons toeach'other preventing the ear from being drawn between them. The ears of corn, after having been thus husked, vwill'pass in succession downthe inclined surface of the aprons, and dropped therefrom at-one end of the machine into a proper receptacle. It will thus beseen that the action of the endless aprons upon the ear, as it descends the inclined plane of their upper surface, will be such as to keep the ear in revolution until a'll its husks have been caught and torn from it. Theoretically speaking, it might besnpposed that as the endless aprons are on the` sume level and travelling at the same rate of speed, the ear' of corn. would not be caused-t0 revolve by them..

In practice, owing tothe rough and irregular surface of the ear and its hnsks, the aprons will act alternately upon it, it being thrown from one to the other, and -thus kept in revolution. I have co ;templatedhowe ver, applying two or more rollers above the revolving drums, which will catch and strip from the cal' such husks as may not have been caught by the endless aprons, should there be any such. It might sometimesliappen that .one end of the ear would be caught by the endless aprons and thrown up into a-vertical position, and stop their revolutions. To remedy this, I apply to opposite sides of the frame a, and so as to extend immediately over the aprons, a range of bars, al a, as shown in tig. 5 of the drawings.. Should the ear be caught at one end, its opposite end, on being thrown upward, would strike against thebars a a, which would prevent the injurious consequences above referred to. In order to reduce the thickness and consequent cost of construction of the elastic aprons, and at the'same time secure sucient elasticity, the shafts pp, before referred to, may be covered with one or more layers of felt, or its equivalent`material. It may be found in practice that more beneficial results may be secured by the-employment of a non-elastic substance for these aprons. Present experience,l

however, would .show that an elastic apron, with either a smooth-or roughened surface, willbe preferable; The boxes or bearings ofthe drums o o should be applied to the frame of 'the machine in an Vadjustable manner, to allow of' the aprons being tightened as occasion may require.

I am aware of yUnited yStates Patent, No.`17,269, and dated May 12, 1857, in which two endless aprons running upward andforming a hopper are employed to loosen the husks about the ear, which with the husks upon it falls upon a. horizontal endless apron, which serves the purpose merely of conveying the ears to the husking rollers. Thesarollers will catch and pull from theear only .such portions of the hnsks as may come in contact with them, as the ear passes directly over them, withoutyas in my invention, making a number of revolutions no as to present all sides of it to the action ofithe husking aprons. I lay'no claim to the subject of such patent.

I claim as my invention the improved stripping and husking machine, as composed of the luted rollers e el,

the hold-back bars r r, thc endless aprons g q, the bridge b4, andi. the horizontal bars al al', combinedsand operating in connection .with the hopper or chute d, substantially in manner as specified.

I also claim the peculiar construction and arrangement 'or combined action of the two stripping-rollers e e, and bars a* r, essentially in manner and for the purpose as before described.

I also claim; in combination with this arrangement of the rollers .e e', and with the chute zi, 'the inclined bars or-hold=backs x 1, substantially'as beforeexplained.

I also claim the employment of the two endless aprons q g as a means of hnsking, or completing the husklng of the earsof corn, in manner and for the purpose as set-fort h.

I also claim, in combination with the endless aprons g q, the transverse bars al al, as and' for the purpose before set forth and explained.
